How's this for an idea? The Journal of American Geriatrics Society has reported great similarities between living on a cruise ship and in an assisted living facility. In fact, the November 2007 issue of the Journal described the "at sea" option as a feasible and cost effective alternative to landlocked living!
The many amenities on a cruise ship, including 3 meals a day, escorts to meals, on board physician, and housekeeping/laundry services rival those of assisted living and for very little cost difference.
For seniors who love to travel, have good to excellent cognitive memory, and who require a little help with activities of daily living, it sounds like an unusual and attractive arrangement.
Factored into the research were life expectancy of seniors moving into assisted living and nursing homes, costs of treating acute illness, medicare reimbursement and other costs.
